Solution Overview
Problem
Current wide gamut RGB digital displays often fail to effectively utilize wide gamut RGB data, resulting in lower image quality due to limitations in brightness dynamic range and color representation, particularly when operating in the RGB color space.
Innovation Solution
A wide gamut RGB digital display system that includes configuration message control logic to indicate and interpret wide gamut RGB indication information and format definition, allowing for the proper reception and display of wide gamut RGB color data, using extended bit depths and color spaces beyond the standard 8-bit RGB scheme.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard gamut RGB displays process wide gamut RGB data using 8-bit color scheme, then device compatibility is maintained, but image quality and color precision deteriorate
Solution Approach 1:
The display system dynamically adapts its color processing capabilities based on the input signal type. When wide gamut RGB data is detected, the system activates extended bit depth processing (10-16 bits per channel) and wide gamut color space transformations, whereas standard signals continue to use the conventional 8-bit pathway, ensuring optimal processing for each signal type without compromising compatibility
Solution Approach 2:
The patent changes the bit depth parameter from the standard 8 bits to extended bit depths (10, 12, 14, or 16 bits) when processing wide gamut RGB data. This parameter change enables precise representation of a broader color gamut while maintaining standard 8-bit operation for conventional displays, thus resolving the contradiction between compatibility and precision
2Measurement precision
If extended bit depths (14 or 16 bits) are used per pixel for brightness dynamic range, then brightness precision is improved, but color gamut utilization deteriorates when not using true wide gamut RGB display operations
Solution Approach 1:
The display system is designed with multi-functionality to handle both standard and wide gamut RGB operations. The same hardware infrastructure supports both 8-bit standard gamut mode and extended bit depth wide gamut mode, allowing the display to universally process different signal types appropriately without requiring separate dedicated systems for each function
3Adaptability or versatility
If signal processing is performed to expand color value gamut from standard input, then color range is improved, but color naturalness deteriorates due to unnatural color expansion
Solution Approach 1:
The patent introduces an intermediary detection and control mechanism that identifies whether the input signal is wide gamut RGB or standard gamut data. Based on this identification, the system selectively applies appropriate processing pathways: wide gamut signals receive genuine wide gamut processing with extended bit depth, while standard signals are processed conventionally, preventing unnatural color expansion and maintaining color naturalness

AI summary
A wide gamut RGB digital display, such as an LCD display, digital television, printer, or any other suitable display, includes wide color gamut configuration message control logic that is operative to indicate, to an image source provider, wide gamut RGB indication information and wide color gamut format definition information that indicates that wide gamut RGB color data is to be received by the wide gamut RGB digital display. The wide gamut configuration message control logic is also operatively responsive to wide gamut confirmation information that is received from the image source provider. The wide gamut RGB digital display also includes logic that is operative to display received wide gamut RGB color data that was received in response to the wide gamut RGB indication information and the wide color gamut format definition information.
